Definitions

  • the present invention relates to an apparatus with at least two parts capable of being moved relative to each other, and which have contact with each other as a result of their relative movement. More particularly, the present invention relates to a valve apparatus with wear-resistant movable parts.
  • a typical prior art valve apparatus contains a magnetic armature which actuates a closing element.
  • the magnetic armature is located in a guiding sleeve surrounded by a magnetic coil, and is capable of displacement therein.
  • the magnetic armature is provided with a plastic coating to improve the gliding quality on the part of the surface which is in contact with the guiding sleeve.
  • prior art devices contain springy attenuating means, e.g., being made of rubber, being installed between the moving parts.
  • An advantage of the present invention is that damage to the movable parts is avoided with little expenditure, even for long operating periods, or with a great number of impacts, by using a thin plastic coating material as the attenuating means, whereby the movable parts can be manufactured at reasonable cost.
  • the parts which are movable relative to each other have a lower specific elasticity than the plastic coating in the area of their impact surfaces. This has the advantage that a large number of materials can be used for the movable parts. Therefore, the material best suited for its performance and cost considerations can be selected for every application.
  • the inventive apparatus when the inventive apparatus is in the form of a valve arrangement actuated by a solenoid, as shall be explained in further detail below, the above-described freedom of selection for the materials offers the particular advantage that magnetically conductive materials can also be used.
  • a low-retentivity material preferably steel, is used.
  • the material used for the coating is a fluorine-containing polymer material, preferably polytetrafluoroethylene (also called TeflonTM).
  • TeflonTM polytetrafluoroethylene
  • the movement of at least one of the parts capable of movement is guided by a guiding device.
  • the contact surfaces of the part guided by the guiding device are also covered, at least in part, with the plastic coating.
  • the part guided in the guiding device can be provided with a coating covering this entire part in one single manufacturing step.
  • the apparatus is configured in the form of a valve arrangement, in which one of the parts capable of movement, relative to another, is provided with a valve seat, while the other part is configured in the form of a valve closing element, with a valve closing surface.
  • the valve arrangement When the valve arrangement is actuated, the valve closing element comes into contact with certain parts of the valve arrangement. Therefore, the valve closing element, and/or the parts of the valve arrangement, are advantageously provided at least in part with the plastic coating.
  • valve seat and the valve closing surface which are associated with each other and serve to close the valve, have areas in which these parts impact against each other and which are therefore provided with the plastic coating as attenuating means.
  • the valve arrangement has a solenoid consisting of at least a coil, a core, and an armature, to actuate the movement of the movable parts.
  • the armature is advantageously configured in the form of a valve closing element.
  • the valve seat can be made in one piece with the core of the solenoid.
  • inventive solenoid may be provided with a yoke through which the magnetic flow is moved from core to armature, in order to improve the degree of effectiveness of the valve arrangement. Thereby, the power consumption of the valve arrangement can be reduced.
  • an apparatus such as a valve arrangement, has at least two parts capable of being moved relative to each other, and which impact against each other as a result of their relative movement towards each other.
  • a thin plastic coating such as polytetrafluoroethylene, is used to cover, at least partially, the impact surface on at least one of the parts having motion relative to the other.
  • the parts which are capable of being moved relative to each other may have a lower specific elasticity (E module) in the vicinity of their impact surfaces than that of the plastic coating.
  • the plastic coating has a thickness of less than 30 ⁇ m and more than 5 ⁇ m.
  • FIG. 1 shows a valve arrangement, in an embodiment of the present invention, as a 2/2-way valve in a sectional representation.
  • FIG. 2 shows a valve arrangement, in another embodiment of the present invention, as a 3/2-way valve in a sectional representation.
  • FIG. 3 shows a detail of the valve arrangement of FIG. 2 in an actuated state.
  • FIGS. 1-3 the same reference numbers are used for the same parts.
  • the valve arrangement embodiments shown in FIGS. 1-3 serve to control a stream of pressure fluid as a function of an electrical signal.
  • the embodiment shown in FIG. 1 is used to switch the pressure fluid stream on and off in one single flow path.
  • the embodiment shown in FIGS. 2 and 3 serves to switch over the pressure fluid stream between two flow paths.
  • the pressure fluid in this case may be compressed air, for example.
  • the electrical signal used may be an electric current, which is switched on and off in accordance with a predetermined time function, in the manner of a digital signal.
  • the valve arrangement has a valve housing consisting of parts (2, 13, 15, 18), which are connected to each other by means of screws (12, 16, 17).
  • the housing parts (2, 13, 15 and 18, respectively) are connected to each other in a pressure-sealed manner.
  • gaskets may be provided on the contact surfaces of these parts, but these are not shown in FIG. 1.
  • An inlet channel (10) for the pressure fluid is provided in the housing part (18).
  • An outlet channel (9) for the pressure fluid is provided in the housing part (2).
  • Pressure fluid hoses for example, may be connected to these pressure fluid channels (9, 10).
  • a part (1) which is movable relative to the valve housing, is located in the valve housing (2, 13, 15, 18), and serves on the one hand as a valve closing element to shut off a flow of pressure fluid between the pressure fluid channels (9, 10), and on the other hand, as an armature in a solenoid arrangement which will be described in further detail below.
  • the valve closing element (1) is provided with a pressure fluid channel (14), through which the pressure fluid is able to flow from the inlet channel (10) to the outlet channel (9) in the open state of the valve, as shown in FIG. 1.
  • the previously mentioned solenoid arrangement is provided with a core formed by a tapering segment (8) of the housing part (15), with a coil (7), and with a yoke formed by the housing part (15).
  • the coil (7) is stationary in relation to the valve housing (2, 13, 15, 18), and surrounds the core (8), as well as a tapering segment of the housing part (18).
  • the coil (7) serves as a movement-actuating device of the valve arrangement, and causes a movement of the armature (1) in the direction of the core (8), when a sufficiently strong electrical current is supplied.
  • the coil (7) is made of an electrical conductive wire.
  • an electrical connection element (22) which is connected electrically to the coil (7), is provided at an opening of the housing part (15).
  • the armature (1) is held in the position shown in FIG. 1 by a spring (11), as long as no current sufficient to overcome the spring force flows in the coil (7). In this state, the valve is open and the pressure fluid is able to flow from the inlet channel (10) to the outlet channel (9).
  • the housing part (15) serves as a yoke of the solenoid arrangement, and provides a magnetic return path for the magnetic field produced by the coil (7) in the core (8), and in the armature (1).
  • the parts (1, 2, 8, 15), which interact magnetically with each other, are made of a magnetically conductive material, e.g., a low-retentivity material, such as steel.
  • the housing parts (13, 18) are made of magnetically non-conductive material, e.g., plastic or brass.
  • the core (8) is provided with a valve seat (4) on the side towards the armature (1).
  • a valve closing surface (3) which is located on the armature (1), is assigned to the valve seat (4).
  • the armature (1) moves in the direction of the core (8) until the valve closing surface (3) impact against the valve seat (4).
  • the valve closing surface (3) presses against the valve seat (4), and thus prevents pressure fluid from flowing through the pressure fluid channels (9, 10). In this position, the valve is closed.
  • valve closing surface (3) and the valve seat (4) serve as impact surfaces.
  • a coating (3a) which is shown greatly exaggerated in thickness, is provided on the valve closing surface (3).
  • the material used for the coating is plastic, which is applied in a relatively thin coat as compared to the dimensions of the armature (1).
  • Polytetrafluoroethylene is preferably used as the plastic, which is applied at a layer thickness between 5 and 30 ⁇ m. Very little coating material is thus consumed.
  • This coating may also be applied to the valve seat (4) as coating (4a), also shown greatly exaggerated in thickness. It is, however, advantageous to apply the coating on the valve closing surface (3), and thereby on the armature (1), because the latter is easier to handle during the coating process as a relatively compact single part. Finally, it is also possible to apply a coating on both the armature (1) and on the valve seat (4).
  • a design is especially advantageous in the case of a valve arrangement with inverse action, i.e., a valve arrangement which is closed when the movement-actuating device is not actuated, i.e., when the coil (7) is without current.
  • One area (5) of the housing part (18) serves as a guiding device for the movable armature (1).
  • the contact surfaces (6) of these parts are also provided with a coating 5a of the type mentioned above.
  • the coating may be applied either on the inside of the guiding device (5), or preferably on the outside of the armature. It is especially economical, e.g., to provide the entire armature (1) with the coating in one working step, e.g., by submerging the armature (1) in the coating material.
  • the embodiment of the valve arrangement is provided with a second outlet channel (21), located in the housing part (13), in addition to the already described parts. Furthermore, a second valve seat (20), which is also located on the housing part (13), is provided, and is assigned a second valve closing surface (19), located on the side of the armature (1) away from the valve closing surface (3).
  • the second valve closing surface (19), in combination with the second valve seat (20), serves to shut off a flow of pressure fluid from the inlet channel (10) to the second outlet channel (21). Thereby, the inlet channel (10) is connected to the outlet channel (9) via the pressure fluid channel (14), when the valve arrangement is in a non-actuated state, as shown in FIG. 2.
  • a coating of the type mentioned earlier is preferably applied to the second valve closing surface (19).
